Us Weekly reports that Skarsgard and Theron, who adopted a baby boy named Jackson in March, had a second date with Skarsgard earlier this month. The two headed to West Hollywood’s Soho House, with friends.

“She rested her head on his shoulder and they looked very couple-y,” a witness tells the magazine.

A source close to Theron told the magazine that the two are involved, but said that they are not necessarily on their way to being a couple.

“It isn’t serious,” the source says. “And no, he has not met the baby.”

Days before Theron announced that she had adopted, the “Young Adult” actress was seen cozying up to Skarsgard at Hollywood gay bar Gym Sportsbar, reports say.

“It was clear they were a couple,” a witness told the National Enquirer, adding that the two sat on the patio holding hands. “After about 45 minutes, they left with their arms around each other.”

Another source supposedly close to Theron told the Enquirer that she was “crazy” about Skarsgard.

“They’ve both been through some bad break-ups and want to keep the romance to themselves for the time being,” the source said. “They figured no one would notice them at a gay bar.”

Theron split with longtime boyfriend Stuart Townsend in 2010, and has since been linked briefly to Ryan Reynolds. Meanwhile, Skarsgard split from his girlfriend of two years, Kate Bosworth, over the summer.
